Gluing Aqueous Coatings

Aqueous Gluing

Two types of adhesives or glues are in common use to glue aqueous coated substrates.  These are cold white glues and hot melt adhesives. The most widely used of these are hot melt adhesives which are a form of solvent-free thermoplastics. These are solid at room temperature and are melted to be applied as a […]

Mystery of Drying Aqueous Coatings

Aqueous Coating

It’s well known and understood that washed clothing dries when the wash water is evaporated.  Similarly, paint dries when the diluent solvent is evaporated, leaving a film of dry paint solids. Aqueous coatings dry as volatile components (mainly water), about 60% of the typical formula composition, evaporate or are absorbed by a porous substrate.  Coalescence […]

Special Effects using Matte, Satin, and Gloss Aqueous Coatings

Special Effects Aqueous Coatings

Aqueous Coatings create Special Effects Many different special effects may be obtained using aqueous coatings that are formulated to provide various levels of gloss. This range in gloss can extend from a very flat matte (reflecting only 15% of light) to very high gloss coatings that are able to reflect as high as 90% + […]
